GUIDE FOR CARD-SETTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 621,988, dated March28, 1899.

Application filed January 11, 1899. Serial No. 701,830. (No model.)

To all whom, it may concern/.-

Be it known that I, ELIJAH AsHwoRTH, machine-maker, a subject of theQueen of Great Britain and Ireland, of the Moss Brook Works,Oollyhurst,Manchester,in the county of Lancaster, England, and also ofFall River, Massachusetts, have invented a certain new and usefulImprovement in Card-Setting Machines, (for which I have mad-e anapplication for patent in Great Britain, No. 15,261, dated the 12th dayof July, 1898,) of which the following is a specification.

My said invention relates to improvements in card-setting machines forsetting the cardteeth in the cloth foundation to produce cardfilleting,as is well understood. In such machines the foundation is conduetedbetween guide-wires provided with adjustable side stops to thefeed-rollers which feed the foundation through the machines, theadjustable stops on the guide-wires serving to guide the foundation tothe feed-rollers. It is found in practice that this method of feedingthe foundation through the machine is subject to a great disadvantage,inasmuch as the foundation is apt to deviate from a perfectly straightline in passing through the machine. Owing to such deviation or lateralmovement of the foundation, it is impossible, without running off theedge, to set the card-teeth close up to the edge of the foundation. Itis customary, therefore, to adjust the card-setting arrangement so thata strip of fabric on either side is left void of teeth to allow for anylateral movement of the cloth. Before the filleting, therefore, is woundupon the carding-engine cylinder the edges of the cloth foundation mustbe pared close to the teeth.

The object of my invention is to provide means whereby the objectionabletendency to lateral movement of the foundation is over.- come, so that Iam enabled to set the cardteeth sufficiently near to theedges of thefoundation to obviate the necessity of paring the same.

The accompanying sheet of drawings more clearly illustrates myinvention.

Figure 1 shows a front elevation of my improved means of guiding thecard foundation to the feed-rollers, together with so'much of acard-settin g machine as is necessary for the clined channel or guide1), formed with turnedup edges 19 b. For varying widths of cardfoundation movable strips 0 of metal are employed, so that a spaceaccurately coinciding with the width of foundation may be readilyobtained. As shown more particularly in Figs. 3 and 4, the metallicstrip 0 is secured to the turned-u p edge of the guide I) by means ofstuds or pins 01 (Z, passing through holes bored in the turned-up edgeI) and secured by means of pinching-screws e e.

To adjust the guide accurately to the width of card foundation, thefoundation is placed within the channel 5; The pinching-screws e areslackened, and the page d are slid in their holes until the metallicstrip 0 is brought to bear against the edge of the cloth foundation, theother edge of the foundation hearing against the other turned-up edge Z)of the channel I). When the requisite adjustment has been obtained, thestrip 0 is secured by the screws e 6.

When the foundation f has been arranged within the guide-channel b, aseparate plate 9 is placed upon the foundation and secured in positionby means of a screw h, provided with a conical end engaging with aconical recess in the plate g, the screw being provided with a lock-nut71. The plates 9 are provided in varying sizes to correspond with thevarying widths of card foundation. The screw h is screwed through acrossbar h, secured to the guide-bracket A. The confining or retainingplate g is adjusted to the thickness of the foundation f by means of thescrew h, being prevented from rising thereby, and beds close upon thefoundation, permitting it to be drawn through the machine as required,but preventing any tendency of the foundation to rise. The sides I) ofthe guide I) also prevent the foundation from deviating in the slightestdegree from a perfectly straight line. By these means a channel isprovided accurately corresponding to the width and thickness of the cardfoundation, as will be more apparent from an inspection of Fig. 4:.

The guide is disposed with its delivery end close up to the nip of thefeed-rollers C C, so that immediately after the foundation is drawn fromthe guide it is gripped by the feed-rollers. The guide-bracket A isprovided with slotsj for the securing-bolts a, so that it may be movedlaterallyto compensate for the wear of the parts used for effecting thelateral traverse of the carriage B.

By means of my improved guide the foundation is conducted in such aperfectly straight path that Iam' enabled to set the card-teeth close tothe edge of the foundation, thus obviating the necessity for any paringof the fabric. The cost of labor of such paring is thus saved, as wellas resulting in economy of material, none of the foundation being out towaste. Moreover, by using card foundation in which the various layersare woven to the requisite width I am enabled to preserve the selvagesuncut, and the-foundation is thus left solid to the edges.

I declare that what I claim is- 1. In combination with a card-settingmachine a guide-bracket A formed with a channel Z), retaining-plate gand means for adjustin g the guide-channel to the width and thickness offoundation, for the purpose of guiding the card foundation to thefeed-rollers substantially as described.

2. As means for guiding card foundation to the feed-rollers ofcard-setting machines, an attachment consisting of a guide-bracketformed with a channel, a movable metallic strip for varying Widths ofcard foundation, a loose retaining-plate, and means for adjusting theretaining-plate to varying thicknesses of foundation, substantially asdescribed.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
